What new features would you add in a non-Amnesia Frictional Games Adventure?

[The Rock Worm]

Feature (?)--Enemies stay
You know, in TDD you can just sit in corner until search music stops, letting you to know that you're safe. There is no need to sneak past the enemies, unlike in Black Plague. I don't ever forget the moments when I had to sneak in dark hallways where the infected patrolled! Even if you changed the area and came back, they weren't gone. I also found Justine to be a bit more scary than TDD because monsters didn't disappear!

I prefer them staying in the area(s), it makes the gameplay harder and scarier.
